I do think he should've been much wiser. Something I didn't get in Nolan's trilogy was how Bruce Wayne never became wiser. Even in the film where the majority of Batfans love, Bruce was still never that bright in TDK. He seemed the wisest in the first film and only seemed like he "dumbed down" with each following film.

Yeah, I agree there. I think he was fine in BB and TDK (although I would've loved more examples of his wits) but in TDKR... it was just bad. I just hated how everyone was outsmarting him. I like that at least in BB he was able to think steps ahead of Earle and was able to buy the Wayne stocks or that in TDK he built the sonar device. It's weird... In TDKR, there was a line about Bruce being very paranoid and yet he's done stuff that a paranoid person won't do.
